Need LUA Script for Bear Guardian Lacerate.

being a bear tank myself, i just use it on cd. not sure what ya wanna get out of it but thats what i do

Well using it on cd is good I do that same but if we could have smash out the stacks and then only refresh the stack when they were about to expire on the target then that would be OP.

then you would want to use the buff stack condition

yeah I know but for some reason it doesn't fire off the attack with the buff stack condition set

Here is a solution to your issue. First Lacerate spell makes sure to get 3 stacks, second one makes it so Lacerate casts if there is 6 seconds or less left on the debuff.
